Web Calculators for Ham Radio Projects
This is my short list of preferred web calculators that i use yo make circuit simulations:

We can make a comparison between the calculators, to be sure of schematic RF values results, but littles differences are normal and will be corrected during pratical construction. You must consider almost a 5 % of tollerance in RF value and, above all, use only a right selection of electronic components.

This is a very fine Software named "SATSAGEN" by Alberto IU1KVL, to use a RTL SDR USB devic like a Spectrum Analizer ed RF instruments with many functions for Ham Radio circuits, from 0 to xxx GHz depending of your usb hardware: https://www.albfer.com/en/satsagen-topics-index/

Utility Software for Ham Radio Download Zip File:
I used this software programs for several goals: projects of circuits, filters calculator, differents design antennas etc. they are in Zip files and most of them have a help menu in English language, the old DOS version is ARRL free programs 90ys. This software is easy to use and run also in WIN PC without trouble. You can also find simple Excell Calculator and in most programs you can print and save the results of calculation. The following links go directly to my public folders on Google Drive.
